Planning the plant list and figured id start w foreground. So heres the question. Baby tears vs staurogyne repens vs hair grass. Ill have a good lighting system and pressurized co2. Ill be using white pool filter sand over some plant spacific substrate. (Havnt chosen yet) There Will be hills and possibly more than one level. Id like to hear what has worked for people. What requirs pruning more than others etc. Oh and I do want an open spot or two so the sand is a part of the scene. Thanks. Any advice is appreciated.
